Abstract
The USEPA is approving the State of Michigan's revision to its State Implementation Plan (SIP) for the Wayne County particulate matter (PM) nonattainment area. The State of Michigan submitted this revision, dated July 18, 1995 to satisfy the contingency measures requirements of section 172(c)(9) of the Clean Air Act (Act). Section 172(c)(9) of the Act requires that States with initial moderate PM nonattainment areas submit contingency measures consisting of specific measures that are not part of the area's control strategy which must take effect without further action by the State or USEPA, upon a determination by USEPA that the area has failed to achieve Reasonable Further Progress (RFP) or attain the PM National Ambient Air Quality Standards (NAAQS) by the applicable statutory deadline.
